Description
JTAG Test Data Output. Serial data output from
the JTAG TAP controller. Sampled on the rising
edge of TCK. If not used, it may be left
unconnected. This pin is muxed with btcx_prisel
(Bluetooth coexistence output, antenna select).
JTAG Mode Select Input. Single control input to
the JTAG TAP controller used to traverse the test
logic state machine. Sampled on the rising edge
of TCK. If not used, it may be left unconnected.
This pin is muxed with btcx_status (Bluetooth
coexistence output, status).
78
I/O
General Purpose I/O pin. This pin is tristated on
(8 mA)
power-up and reset. Subsequently, it becomes
an input or an output through software control.
A programmable PU or PD resistor is available
for each GPIO pin. This pin is muxed with
wlan_led (WLAN LED output).
79
I/O
General Purpose I/O pin. This pin is muxed with
mimophy_core0_ant_shd (antenna switch
control for the shared [middle] antenna of a 2 of
3 design
[core 0]).
80
I/O
General Purpose I/O pin. This pin is muxed with:
• mimophy_core1_ant_shd: antenna switch
control for the shared (middle) antenna of a
2 of 3 design
(core 1).
• btcx_freq: Bluetooth coexistence RF
frequency
81
I/O
General Purpose I/O pin.
82
I/O
General Purpose I/O pin. This pin is muxed with:
• ext_lna_2g_pu_0: 2.4 GHz band core 0
power amplifier control
• ext_pa_2g_0: 2.4 GHz band core 0 power
amplifier control
• CS: SPI select
84
I/O
General Purpose I/O pin. This pin is muxed with:
• ext_lna_2g_pu_1: 2.4 GHz band core 1
power amplifier control
• ext_pa_2g_1: 2.4 GHz band core 1 power
amplifier control
• SCLK: SPI clock
• I2C_SCL: I²C clock
